We're all a bit cynical of the diet claims we see and hear each day. There always seems to be a new pill or fad diet promising magic results on the market.

Dr. Roy Walford, the late University of California, Los Angeles (UCLA) gerontologist noted for his studies on the affects that diet has on longevity, discovered that by reducing the caloric intake of laboratory mice by 40 percent, their lifespan nearly doubled from 24 to 36 months. Not only was their life extended, but they also maintained the mental and physical characteristics of mice one-sixth their age.
